Bricks:

An imperial standard brick is 9 inches long, 4 1/2 inches wide and 3 inches deep.

A metric brick is 8.86 inches long (225mm) 4.43 inches wide (112.5mm) and 2.95 inches deep (75mm)

This makes the metric brick marginally smaller than its imperial counterpart and the difference, when joining new to old, must be taken up with an increase in the mortar joints.

There are 60 bricks to 1 square metre and you will use approximately 0.022 cubic metres of wet sand and cement to lay them with 10mm joints, this is equivalent to approximately 60kg.

Blocks:

A normal block is 2 bricks long, 3 bricks high and one brick wide (when laid with 10mm joints)

There are approx. 10 blocks to 1 square metre and you will use approx 0.012 cubic metres of wet sand and cement to lay them with a 10mm joint. This is equivalent to 31kg.
